This phrase includes the words you choose.

Using extensive matching, when the search words of netizens are highly related to your keywords, even if you don't submit these words, your promotion results may get a chance to be displayed.

Taking the keyword "English training" as an example, under the extensive matching mode:

Search words that may trigger promotion results include:

1) Synonyms: English training, English training.

2) Related vocabulary: foreign language training English summer training

3) variant forms (for example, adding spaces, reversing word order, typos, etc.). ): English training, summer training English.

4) phrases that completely contain keywords (the word order cannot be reversed): English training summer school, which English training institution is better?

Using phrase matching, when a netizen's search term completely contains your keyword, and your keyword (including synonyms of keywords) is inserted or inverted, the system may automatically display your promotion results.

Taking the keyword "English training" as an example, in the default phrase matching mode:

1. Search for words that may trigger the promotion results: English training, English training summer school, which English training institution is good, English training, English-related training, English training, English training.

2. Search words that cannot trigger promotion results include: English songs and computer training.

By changing the phrase matching control character to [] and displaying it as [keyword] on the keyword setting page, only phrases with complete and accurate keywords will be matched. This setting may lose some valuable search traffic, so please be careful.

Compared with extensive matching, phrase matching will not only locate potential customers more accurately, but also lose many exhibition opportunities. I suggest you use it with caution.
